Other interest: native to temperate regions; name from Latin
iuncus for rush which is from iungere meaning to join, refering
to its ancient use in tying; may be confused with the true Bulrush Scirpus
(as supposedly cradled the infant Moses), with the main ornamental
species tabernaemontani now placed in the genus Schoenoplectus,
these genera similar in leaf but different in flower and less hardy
than Juncus

Other culture: most species grow wild and are considered weeds
this species and cultivars having some ornamental value; plant in submerged
tubs to prevent invasive spread by rhizomes

Propagation: spring division

Species:

There are several other species of the genus that may be found less
commonly, including:

glauca--Blue Rush, 1-2', similar to effusus but bluish
foliage

macrophyllus--Flat-bladed Rush, 1-2', dark green stems with small
clusters of pink and white flowers in spring

Cultivars:

'Carmen's Japanese'--Green Rush, 2-3', bright green and narrow leaves

'Spiralis'--Corkscrew Rush, 1-2', stongly spiralling or corkscrew stems,
